"works very nice with my android phone and laptop with windows 7, sound that's all right above average, pretty loud if you maximize the volume in both devices phone and headset at the same time, overall very satisfied with this purchase."
"The hinges, to fold the headphone for the sake of mobility, and the plastic material surrounding it break so easily. They are meant to be advantage but in practice it is a design flaw. Battery life is decent. There are some connectivity issue, specially with Windows, sometimes it gets randomly disconnected. Sound quality for music playing is good for the price of the device, but not at all acceptable as a headset. The microphone always picks up the sound from the speakers, causing the other side to hear their own reverberated voice. Overall, if you are an all time bluetooth headphones/headsets user and you can afford a higher quality one, don't get this one, but for occasional music appreciation on the go or while biking, it is a decent working device."
"I really wanted a pair of headphones that were wireless, so when these came on sale, I wanted to try the product out. I've bought a lot of another Lenovo products and have been very happy, but not these headphones. They are indeed bluetooth wireless and the battery life is impressive, but the audio quality is terrible. It sounds muffled and scrambled even when I sit directly in front of my laptop. The quality goes down even further as I step away from my laptop."
